The present invention relates to a hydrogen charging method of a fuel-cell vehicle, and provides a hydrogen charging method of a fuel-cell vehicle, which is configured to charge a hydrogen tank of the fuel-cell vehicle by sequentially using a plurality of storage tanks (hydrogen storage tanks provided in a charging station) having different pressures, and which is capable of being quickly and safely charged up to the maximum charge amount even if the pressure and temperature of the hydrogen tank cannot be confirmed from the fuel-cell vehicle because an error occurs in the communication between a hydrogen charger and the fuel-cell vehicle. To this end, in terms of a hydrogen charging method in a hydrogen charging device having a low-pressure storage tank, a middle-pressure storage tank, and a high-pressure storage tank, the present invention is configured to charge the hydrogen tank of the fuel-cell vehicle by sequentially using the low-pressure storage tank, the middle-pressure storage tank, and the high-pressure storage tank.
본 발명은 연료전지 차량의 수소 충전 방법에 관한 것으로, 서로 다른 압력을 갖는 복수의 저장탱크(충전소에 구비된 수소 저장탱크)를 순차적으로 이용하여 연료전지 차량의 수소탱크를 충전함으로써, 수소 충전기와 연료전지 차량 사이의 통신에 에러가 발생하여 연료전지 차량으로부터 수소탱크의 압력과 온도를 확인할 수 없는 경우에도 신속하고 안전하게 최대 충전량을 충전할 수 있는 연료전지 차량의 수소 충전 방법을 제공하고자 한다. 이를 위하여, 저압 저장탱크와 중압 저장탱크 및 고압 저장탱크를 구비한 수소 충전기에서의 수소 충전 방법에 있어서, 저압 저장탱크와 중압 저장탱크 및 고압 저장탱크를 순차적으로 이용하여 연료전지 차량의 수소탱크를 충전하는 것을 특징으로 한다.
